本文介绍了Thymeleaf中如何使用th:fragment、th:include、th:replace和参数化模板配置进行页面复用。通过实例展示了如何引入公共头文件，并探讨了使用Vue.js进行分页的实现方式。详细讲述了如何查找和配置Thymeleaf模板路径，以及在实际项目中应用这些技巧。

1. 概述

在web开发中，我们经常会将公共头，公共尾，菜单等部分提取成模板供其它页面使用。在thymeleaf中，通过th:fragment、th:include、th:replace、参数化模板配置、css选择器加载代码块等实现。下文通过例子来说明用法:

fragment语法
通过 th:fragment 和 css选择器加载代码块
th:include 和 th:replace
参数化模板配置

Thymeleaf基本搭建和配置可以参考其他网站的配置实例，这里不详细说明。

2.引入头文件

首先我们讲述web项目里的js，css如何放到一个公共页面，用thymeleaf模板语法调用呢？其实thymeleaf里有个标签可以使用：

initHead.html

<th:block id="initHead"><!-- 可以充当HTML标签，但在模板执行后该标签会消失 -->
<meta charset="UTF-8" />
<meta http-equiv="Content-Type" content="text/html;charset=UTF-8"/>
<script type="text/javascript" th:src="@{/resources/js/share/backstage/jquery.js}"></script>

<!-- jqueryUI -->
<script type="text/javascript" th:src="@{/resources/js/share/jquery-ui-1.12.1.custom/external/jquery/jquery.js}"></script>
<link th:href="@{/resources/js/share/jquery-ui-1.12.1.custom/jquery-ui.css}" rel="stylesheet" type="text/css" />
<script type="text/javascript">
var rootPath = "/{项目名}";
</script>
</th:block>

homepage.html

<!DOCTYPE HTML>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<title>主页</title>
<th:block th:replace="common/base/initHead :: #initHead"></th:block><!-- 调用模板 -->
<script language="javascript">
$(function() {});
</script>
</head>
<body class="homepage_body">....common/base/initHead :: #initHead"></th:block><!-- 调用模板 -->
<script language="javascript">
$(function() {});
</script>
</head>
<body class="homepage_body">....

问题来了，我们如何找到initHead.html文件呢？

其实也是通过配置的thymeleaf路径下查找。例如我配置了

<!-- 使用thymeleaf解析 -->  
<bean id="templateResolver" class="org.thymeleaf.spring4.templateresolver.SpringResourceTemplateResolver">  
	<property name="prefix" value="/thymeleaf/" />  
	<property name="suffix" value=".html" />  
	<property name="templateMode" value="HTML" />  
	<property name="cacheable" value="false" /> 
	<property name="order" value="#{T(org.springframework.core.Ordered).HIGHEST_PRECEDENCE}" /> 
	<property name="characterEncoding" value="UTF-8"/>
</bean>

配置了thymeleaf查找路径是“/thymeleaf/”

加上红色部分的路径，那么initHead.html文件的路径就必须是“WebRoot/thymeleaf/common/base/initHead.html”

3.分页

分页我使用vue.js的分页插件

道理和上面一样，附上源码：

pageInfo.html

<th:block id="pagin" th:fragment="pagin (refreshForm)">
<style type="text/css">
.page {font-weight: 900;height: 40px;text-align: center;color: #888;margin: 20px auto 0;background: #f2f2f2;}
.pagelist {font-size: 0;background: #fff;height: 50px;line-height: 50px;}
.pagelist span {font-size: 14px;}
.pagelist .jump {border: 1px solid #ccc;padding: 5px 8px;-webkit-border-radius: 4px;-moz-border-radius: 4px;border-radius: 4px;cursor: pointer;margin-left: 5px;}
.pagelist .bgprimary {cursor: default;color: #fff;background: #337ab7;border-color: #337ab7;}
.jumpinp input {width: 55px;height: 26px;font-size: 13px;border: 1px solid #ccc;-webkit-border-radius: 4px;-moz-border-radius: 4px;border-radius: 4px;text-align: center;}
.ellipsis {padding: 0px 8px;}
.jumppoint {margin-left: 30px;}
.pagelist .gobtn {font-size: 12px;}
.bgprimary {cursor: default;color: #fff;background: #337ab7;border-color: #337ab7;}
.pagelist .jump.disabled {pointer-events: none;background: #ddd;}
.page_select {width: 50px;height: 30px;border: 1px;border-style: solid;border-color: #d5d5d5;border-radius: 5px;}
</style>
<div id="pagePlugIn">
	<div>
		<div class="page" v-show="show">
			<div class="pagelist">
				<span class="jump" :class="{disabled:pstart}" @click="pageUp()">上一页</span>

				<span class="ellipsis" v-show="efont">...</span> 
				<span class="jump" v-for="num in indexs" :class="{bgprimary:current_page==num}" @click="jumpPage(num)">{{num}}</span>
				<span class="ellipsis" v-show="ebehind">...</span> 
				<span :class="{disabled:pend}" class="jump" @click="pageDown()">下一页</span>
				<span v-show="current_page<pages-4" class="jump" @click="jumpPage(pages)">{{pages}}</span> 
				<span class="jumppoint" >共<span style="color: red;" th:text="${pageInfo.totalCount}"></span>条记录</span>
				<span class="jumppoint">页大小：</span>

					<option value="20" th:selected="${pageInfo.pageSize eq 20}">20</option>
					<option value="50" th:selected="${pageInfo.pageSize eq 50}">50</option>
					<option value="100" th:selected="${pageInfo.pageSize eq 100}">100</option>
				</select>
				<span class="jumppoint">跳转到：</span>
				<span class="jumpinp"><input type="text" v-model="changePage"></span> 
				<span class="jump gobtn" @click="jumpPage(changePage)">跳转</span>
			</div>
